CAD 120S

The stereo vacuum tube power amplifier has a great history at Cary Audio Design. The previous generation Rocket 88 R and the V 12R power amplifiers garnered fantastic reviews for stable power output, incredible value for the money and sound quality along with best buy and ‘Class A’ ratings from magazines and reviewers worldwide. Building on this storied legacy, we are releasing the CAD 120S stereo vacuum tube power amplifier. This innovative stereo power amplifier is rated at 60 watts per channel in triode mode and 120 watts per channel in ultralinear mode into an 8 ohm speaker load.

Full rated output power is from 17 Hz to 23 kHz with less than 1% total harmonic distortion. The output stage may be switched ‘on the fly’ from triode mode to ultralinear mode by using a front panel selector button. There are LED lights above the mode selection button to show which mode the power amplifier is working in for visual confirmation.

The vacuum tubes in each channel consist of one (1) 6SN7 for the input stage, one (1) 6SN7 for the driver stage and four (4) KT 88 output power tubes. The circuit is a Pure Balanced design with separate RCA and XLR inputs. A soft start turn on circuit is built-in for long life and easy turn on in large systems. The power supply features 1,120 micro farads of capacitance for ample reserves in demanding usages. The output transformers and the power transformer have a single cover painted to match the chassis.

The backlit front panel meters indicate the circuit bias setting for each channel and visually indicate proper operation for the CAD 120S amplifier.
